sigsegv Fault

UNIX Solaris
1

I receive a sigsegv failure. I was under the impression that a core file is created everytime a sigsegv occurrs and the process is terminated. I have had two recent occurrances of a core file not being created. Does anyone know why a core file would not be created.

The creation of core files can be controlled by the coreadm command. See Man Page for coreadm (OpenSolaris Section 1m) - The UNIX and Linux Forums

In addition, core files won't be created if:

  • the current directory isn't writable due to permissions
  • its file system is full or mounted read-only
  • the coredumpsize ulimit is set to zero
